In the ordinary PCB design, we will encounter all kinds of safe spacing problems, such as the spacing between vias and pads, the spacing between traces, and so on, which we should consider. In PCB design, we divide these spaces into two categories: Electrical spacing Non-electrical safety spacing I. PCB design electrical safety spacing 1. […]

1. Spacing between patches The spacing between chip components is a problem that engineers must pay attention to in layout. If the spacing is too small, it is very difficult to print solder paste and avoid soldering. Suggested distances are as follows Device distance requirements between patches: Same device: ≥ 0.3mm. Heterogeneous devices: ≥0.13*h+0.3mm(h is […]

Electronic component surface cleaning and dust removal treatment When plasma technology is applied to circuit board cleaning, because the particles in plasma have a very high speed, it can effectively remove the impurity particles attached to the surface, and its purification effect is better than that of conventional treatment systems. At the same time, plasma […]
